lshutters 4for the fronts of radiators of auto-v mobiles and other motor vehicles.

One object of my invention is to make the shutter mechanism-of the sliding plate type, as distinguished from the pivoted vane type, and to so construct and arrange the plates 'that a greater area of theradiator core will be exposed to the coolin leffect of the air when .the shutter is ful y o en than possible with the cPilate ty e of s utter` as heretofore employe ,thus a lowin my 1m roved shutter mechanism to be app ied to t e radiator as a permanent xture for all the year use and avoid the necessity of removing the shutterI from the radiator in the warm weather and replacing it in cold weather as required with late shutters heretofore made.

Another ob]ect of my invention is to provide my improved shutter mechanism with a lurality of plates, one stationary andthe other two movable with respect to each other and to the stationary plate so that the openings or slots inthe plates may be'made wide enough to expose at least two-thirds of the shutter is fu ly open, and thus insure a. more eicient cooling of the core than with the plate shutters as heretofore made.

A further obect 4ofmy invention is to connect the movab e'plates together so that they will balance one another when lmoved and further enable the use of only one actuatf .in'ghpart `:for both plates.

e invention consists further in the matters hereinafterV described and more particularly set forth in the a pended claims.

In the accompanying rawmgs- Fig. 1 is a side-view, with arts away, of a radiator and hoody o an automobile and showing applied in front of the ra' ates or radiator core whenthe broken viewstakenl through the shutter plates, and

lshowing the same in fully open, partially open, 'and fully closed positions, respectively.

In the drawings, 1 indicates a radiator of an automobile or other motor vehicle. The radiator is of the Ausual type for handling cooling water, and comprises, generally, upper and lower tanks 2, 3, a core 4 interposed between and opening into said tanks, and an outside casing'or shell 5 surrounding said tanks and core,` and containing the same. The core .4 is indicated inthe conventional form, but it is to be understood' that it may be of, the-honeycomb, cellular, fin and tube, or such other type usually made to allow currents of air to pass therethrough for cooling the water passing through the same. l

For controlling the passage of air through the core Il, I provide a shutter mechanism constructed as follows. Said mechanism comprises a plurality of vertically arranged shutter plates, there being three of said plates 6 7, and 8 in the form of shutter shown in the drawin s. These plates are all flat and are arrange with the plate 7 fixed against vertical as well as lateral movement and located between the other two, 6 and 8. The latter are movable vvertically with respect to each other and to the fixed or stationary plate 7, and thus slide up and down on the latter.

The plates 6, 7, and 8 have substantially the same shape and that'is made to conform with the shape of the front face of the core 4. The plates have substantially the same width horizontally, and the movable plates 6 and Shave substantially the'same length vertically. The stationary plate 7, however,

is slightly longer vertically than the movable plates so that the latter may have move-v ment vertically within the retainingcasing `or frame 9 extending about' the shutter mechanism, as shown in the drawings.

one against the other, l

- The shutter mechanism is of a size toje`xtend horizontally and vertically over the .front face ofthecore 4 and, inthe form of construction shownv in the drawings, is secured to the core by fastening bolts 10, 10

rinserted through the plates and into and through the core4 and. having clamp nuts a plied thereto on the inside of the core, as slliown in Figs. 3 and 5. These bolts 10, 10' extend through vertically arranged, elongated slots 11, 111 in the movable plates 6.

and 8,'so Athat these plates may be slid up and down .without'the bolts stopping them.

The marginal frame 9 is -secured to and carried by the stationary plate 7. Each of the plates 6, 7, and 8 has a plurality of elongated slots or openings 6, 7 and 8, respectively. These in the construction shown extend horizontally across the plates and are arranged in two vertical rows in each plate and all register when the shutter is fully open, 'as shown in Figs'. 2, 3, and 6.' To partially close the shutter, the plates 6 and 8 are moved vertically, one up and the other down to bring their openings 6a and 8a slightly out of register with the openings 7** in the stationary plate 7 as shown in Fig. 7.

To fully'7 close the shutter, the plates 6 and 8 are moved in the same direction until the upper edges of the openings 6 in the` late 6 are aligned with the bottom edges o the openings 8EL in the plate 8, as shown in Fig. 8.

By the use of three plates, one stationary and the other two movable as described, the

openings or slots in said plates may be made vertically wider than when only two plates are used as heretofore, because instead of rei quiring one plate to close these openings in the stationary plate as heretofore, two plates are emploed to close these openings, 'thus allowing t e latter to be made twice as wide. This results in allowing practically twothirds of the area of the core 4 to be exposed to the air currents when the shutter is fully open. Thus the core 4 may function eiiciently and properly as such a small portion of its area is covered by the imperforated parts of the plates, when the shutter vis fully l open, that the eect of the parts on the cool- 1ng action ofthe core ris fairly negligible. Manifestly, my' improved shutter may be attached to the radiator as a permanent tixture and be left on in cold as well as in warm weather, because when the shutter is fully open enough air is allowed to pass through the core to carry off sufficient radiant heat even in the hottest weather, which is not the case, however, with shutters asl heretofore made,because full one-half of the area of the core is covered y the imperforated parts of the shutter when fully open, thus making it necessary to remove them from the radi-K- ator in warm weather. For moving the plates 6 and 8, I provid a shaft 12. This extends from the dashboard 13 to and through the core 4, as shown in Fig. .1. At the dash-board, the shaft 12 has apart 14 bv which t-may be conveniently turned., The other end of said shaft extends through and is journaled inthe stationary plate. 7 and also through the plate 6, the` latter having a vertically elongated slot 15 to receive the shaft and permit said plate 6 to move with respect to said shaft.

Fixed to the front end of said shaft 12 vare two arms 16, 17, the latter being between moese? the plates 7 and 8, as clearly shown in Fig. 4. These arms extend on opposite sides 'of said shaft 12 and both have a pin and slot connection 18, 19, respectively, with the associated plates 6 and 8. Thus, when the shaft 12 is turned, the plates 6 and 8f are moved up and down, respectively. to either open or .close the slots 6a, 7, and 8a, or to partially open or close them, as is apparent.-

The connection of both plates with the shaft 12 and moving one plate up and the other vfrom the spirit and scope of my invention.`

I claim as my invention:

A shutter mechanism of the character described, comprising three Vplates arranged one a ainst the other, said plates having a plura'1ty of openin therein, comprising, substantially two-thlrds of the total area of the plates, one of said plates being stationary and the other two being movable with respect to each otherand to said stationary plate for opening and closing the openings 1n said plates, and means lfor moving said movable lates.

2.
